(I work in a discount supermarket and usually we’re three people on one shift, but today we’re suddenly one worker short. I am walking towards the till where a couple of customers are waiting. Another customer asks me a question as I am walking and I stop for a second to answer her, when I suddenly hear a loud whistling sound.)

Customer:*clearly a bit tipsy, even though it’s only nine am* “HEY! God, that was slow!”

Me:*already at the counter, scanning another customer’s items* “I’m sorry, but we’re really understaffed today. I promise I’m going as quickly as I can!”

Customer: “Yeah, yeah, whatever. It just cannot be that you take such a long time to come over and take care of paying customers!”

(The customer I’m currently dealing with laughs nervously and is clearly uncomfortable.)

Me: “Well, we cannot be everywhere when we’re short on staff and so many products are waiting to be put on shelves, but I am just going to go really quickly with your items here so you can get out of here and enjoy the day!”

(I keep smiling and scan his items in a jiffy. All the while he keeps ranting about how insane it is that I was so slow to serve him. As the time for him to pay comes…)

Customer:*fumbling in all his pockets* “Oh, it seems I cannot find my wallet… Just hold on a sec.”

Me:*jokingly* “Well, I guess it’s your turn to be slow now!”

(The customer looked up at me with a VERY embarrassed look on his face while he kept fumbling for his money, holding up all the other customers in line. He never found the money and left the store with his head low, mumbling apologetically. Even though he didn’t apologize, he clearly realized his hypocrisy and was VERY quiet when he came back with the money. This totally made my otherwise stressful day.)
